after my other thread, its become apparant that its nearly impossible to compare cams just by name and manufacturer. most people end up wanting one came due to its namesake but buying another because of its price tag or foregoing that cam for a regrind from a 3rd party because it seems possible to get the same cam as the 1st (expensive) option at a fraction of the price because it has the same "name"... only to find out its not the same animal. i think we need to start a list of cam cards for future reference so we arent just playing a name game when it comes to picking cams.

how bout this format for entering all the pertinant info (or a clear picture of your cam card);
